Pinpoint Test B: All Passenger Power Windows are Inoperative

Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number

Normal Operation

Under normal operation, the RH front, LH rear and RH rear power window motors receive low current power through circuit CBP41 (BU). When the LH front window control switch is in the UNLOCK position, voltage is supplied to the RH front, LH rear and RH rear window control switches through circuit CPW14 (VT/WH).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- LH front window control switch
